FUEL CAP
WARNING:
A leaking fuel cap is a fire hazard and must be
replaced immediately.
The fuel cap contains a non-serviceable filter and a check
valve. A clogged fuel cap will cause poor engine perfor-
mance. If performance improves when the fuel cap is
loosened, check valve may be faulty or clogged. Replace
fuel cap if required.
CHANGING ENGINE OIL
(Fig. 11)
Engine oil should be changed after every 25 hours of use.
Change the oil while the engine oil is still warm, but not hot.
This allows the oil to drain quickly and completely.
Remove the oil fill cap/dipstick.
Tip mower onto its side and allow oil to drain from the
oil fill hole into an approved container.
Place mower upright and refill with oil following the
instructions in the
Adding/Checking Oil
section.
NOTE:
Used oil should be disposed of at an approved dis-
posal site. See your local oil retailer for more information.
SPARK PLUG MAINTENANCE
(Fig. 12)
The spark plug must be properly gapped and free of depos-
its in order to ensure proper engine operation. To check:
Remove spark plug boot.
Clean any dirt from around base of spark plug.
Remove spark plug using a 13/16 in. spark plug socket
(not provided).
Inspect spark plug for damage, and clean with a wire
brush before reinstalling. If insulator is cracked or
chipped, spark plug should be replaced.
NOTE:
If replacing, use the following recommended
spark plugs or equivalent: Torch F6RTC or NGK
BPR6ES.
Measure plug gap. The correct gap is .028
−
.031 in. To
widen gap, if necessary, carefully bend the ground (top)
electrode. To lessen gap, gently tap ground electrode
on a hard surface.
Seat spark plug in position; thread in by hand to prevent
cross-threading.
Tighten with wrench to compress washer. If spark plug
is new, use 1/2 turn to compress washer appropriate
amount. If reusing old spark plug, use 1/8 to 1/4 turn
for proper washer compression.
NOTE:
An improperly tightened spark plug will become
very hot and could damage the engine.
Reinstall spark plug boot.
MAINTENANCE
DRIVE GEAR MAINTENANCE
(Fig. 13)
To ensure smooth operation of wheels, the wheel assembly
should be cleaned before storage.
Remove the nut and wheel and set aside.
Remove dust cover, e-ring, washer, pins, and wheel gear.
Clean any dirt from these items and the end of the drive
shaft by wiping with a dry cloth. If necessary, rubbing
alcohol may be used to remove any stubborn dirt.
WARNING
Do not lubricate any of the wheel components
Lubrication may cause the wheel components
to fail during use, which could result in mower
damage and/or serious personal injury to the
operator.
Reinstall wheel gear with the arrows facing the front
of the mower. Reinstall pins, washer, e-ring, and dust
cover.
Reinstall wheel and nut. Tighten nut to secure.
STORING THE MOWER
When storing the mower for 30 days or more:

directions to add stabilizer to petrol in fuel tank. Run
engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor.

tank inside a building where fumes may reach an
open flame or spark.
If not using fuel stabilizer, allow the engine to run until
the mower is completely out of petrol.
Once the engine has stopped, allow the blade to come to
a complete stop and disconnect the spark plug wire.
Turn mower on its side (with carburetor facing up) and
clean grass clippings that have accumulated on the
underside of the mower deck.
Wipe the mower clean with a dry cloth. Do not use a
garden hose or pressure washer to clean the mower.
Check all nuts, bolts, knobs, screws, fasteners, etc., for
tightness.
Inspect moving parts for damage, breakage, and wear.
Have repairs made on any damaged or missing parts.
Store the mower in a well-ventilated area that is clean,
dry, and out of the reach of children.
